As already has been posted by multiple users, each post in this thread has the proper time/date stamp. Clearly the issue is on your end, not the site. There is absolutely no evidence (other than your "gut feeling") that there is anything amiss with either of these users.
As I told you in private message, Becca12 has not posted publicly here since 2020 so unless you have been messaging her privately [and I would have serious questions about why a 70 year old man (according to the information you provided to the site) is private messaging with a 21 year old female] there is no way you were almost scammed by her.
